1. It is critical that your Easy Fly 40 is bal-
anced correctly. Incorrect balancing may
cause loss of control and a crash. The
centre of gravity is located 9cm from the
leading edge of the wing. The Easy Fly
40 should be balanced with an empty fuel
tank.
2. Apply 2 pieces of masking tape to the
underside of the wing, and mark the cen-
tre of gravity on the tape ( 9cm from the
leading edge of the wing).
3. Place your fingertips on the marks
underneath the wing and carefully lift the
airplane.
4. If the tail falls, correct it by adding
weight to the front of the fuselage. If the
nose falls, correct it by adding weight to
the rear of the aircraft.

Control Throws.
Aileron - 10mm up and 10mm down
Elevator- 10mm up and 10mm down
Rudder- 20mm left and 20mm right
CONTROL SURFACE THROWS
The ailerons should move up 10mm and down 10mm. If the movement is excessive,
move the nylon clevice out one hole on the control horn until the control movement is
ideal.
The elevators should move up 10mm and down 10mm, again if the movement is exces-
sive, move the nylon clevice out one hole on the control horn, away from the control sur-
face.
The rudder should move left 20 mm and right 20mm, if the movement is not enough,
move the clevice in one hole closer on the control horn.
*NOTE. Pushrod clevices can sometime work loose on the metal pushrods, so it is rec-
ommended when all control surfaces throws have been set to the ideal, place a drop of
CA glue onto the metal pushrod thread to securely fix the nylon pushrod clevice into
place.
FLIGHT PREPARATION
Operation and Direction of the control surfaces.
- Turn on your radio transmitter.
- Then turn on your receiver.
(a) Check ailerons whilst standing behind the airplane, move the aileron stick to the right,
the right aileron should move up and the left aileron should move down. If not, then
switch the reversing switch on your transmitter.
(b) Check the elevator. Pull back on the elevator stick, the elevator should move up, then
push forward on the elevator stick, the elevator should now move down. If not then
switch the reversing switch on your transmitter.
(c) Check the rudder. Whilst standing behind the airplane move the rudder stick to the
right, the rudder should move to the right. If not switch the reversing stick on your
transmitter.
(d) Check the throttle. Push the throttle stick forward, the carburettor barrel should open
fully, without binding or excessively flexing the throttle cable, pull the throttle stick.
back and the carburettor barrel should close. If not then switch the reversing switch
on your transmitter.
